To all whom it may concern Be it known that I, EDWARD D. MILL- HOUSE, a citizen of the United States, residing at Peru, Miami county, and State of Indiana, have invented and discovered certain new and useful Improvements in Concrete-Vault Molds, of which the following is a specification.

My said invention consists in certain improvementsvin the details of construction and arrangement of parts of steel molds designed especially for forming burial vaults, whereby certain advantages and improved results are secured in the operation of the apparatus,and in the product, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a top or plan view of the portion of the vault mold for forming the body of the vault, adjusted and in position for use, the central portion being broken out in order to show the structure on an enlarged scale, Fig. 2 a side elevation thereof, Fig. 3 a longitudinal section on the dotted line 3-3 in Fig. 1, Fig. 4 an end elevation, the central portion being broken away, Fig. 5 a cross section on the dotted line 5-5 in Fig. 1, Figs. 6, 7, 8, 9, 10, and 11, detailed views illustrating a means for clamping and securing the mold sections together at the corners, Fig. 12 a side elevation of the mold section for forming the lid of the Vault, Fig. 13 a top or plan view thereof, Fig. 14 a longitudinal section on the dotted line 14-14 in Fig. 13, Fig. 15 a partial end elevational view, Fig. 16 a cross section on the dotted line 1616 in Figs. 13 and 14, Fig. 17 a detail View, and Fig. 18 a cross section through a vault illustrating the form of vault which my improved mold is designed to make.

In said drawings, like reference characters indicate corresponding parts throughout the several figures thereof.

The body of the vault is formed by the mold illustrated in Figs. 1 to 11 inclusive, said mold consisting of an outside structure, a core, and means for adjusting the parts in relation to each other.

The outer structure comprises two end sections 10, and two side sections 11., each of which is preferably composed of sheet steel formed with out-turned horizontal flanges on their upper. and lower edges and with a recess a midway the height of each sectlon of an appropriate cross-sectional shape to form the external ledge 01. on the exterior of the body portion A. of the vault as lllustrated in Fig. 18. At intervals around said sections, vertical braces 12 are interposed between the upper and lower flanges of said central sections, being riveted thereto and formed of angle ron as indicated.

On the top flange at one end of each end section 10 a clamping bolt supporting clip 13 is riveted, having two branches 14 and 15, spaced apart, and provided with apertures in line with each other for receiving and supporting the clamping and securing bolts 16. One end of each section 11 is also provided with corresponding supporting clips 13 riveted to the top flange thereof. A.

series of holes 17 are formed in the top flange of the respectivesections 10 and 11 adjacent to the ends of the other sections carrying said supporting clips 13. Said perforations 17 are formed normally slightly to one side of, or out of line with, the perforations in the branches 14 and 15 of the clips 13. The pins 16 are formed tapered on one side as best illustrated in Fig. 6, so that the point will extend into the perforations 17 while said perforation overlaps the holes in section 14 and 15 but slightly. As the pin is then forced to position from that shown in Fig. 6 to that shown in Fig. 8, the corner joint between said sections 10 and 11 will be tightly drawn and secured together. The two part clips afford a support for the pins of suflicient bearing to hold said pins in vertical line and secure the drawing action.

At the lower corners an car 18 is riveted to one end of each section which is adapted to project through a corresponding slot 19 in the adjacent part. A tapered pin 20 is adapted to project through the perforation in said ears and when driven in is adapted to draw the lower corners tightly together and secure them in place. The slots 19 in the lower corners correspond in position to the holes 17 in the upper flanges and by withdrawing the pins16- and 20 and adjusting the diagonally opposite corners of the structure, any width or length of the structure can be secured, as will be readily understood.

The core of the mold is also formed of sheet steel of the form desired with int-urned flanges on their top and bottom edges and consists of corner sections 21, end telescoping sections 22 and'side telescoping sect1ons 23. Angle bar braces 29 are riveted between the top and bottom'fianges. A series of holes 24 are formed through the top and bottom flanges of said overlapping" sections and vertical rods 25 are inserted through said holes to secure said several parts to-' '26 which are bolted to the flanges of the core and have ends which project beyond the top of said outside structure. Tn practice the concrete or" vwhich the bottom of the vault is made is first deposited within the outside structure to aidepth approximately the distance representing the difference in height between the outside strupture and'the core. The core is then placed in position within the outside structure and the space between the core and the outside filled with concrete and tamped in place and allowed to set, when the various sections composing both the outside structure and the core are sepa rated by removing the holding pins and rods and the finished body of the vault is formed. I

Telescopic brace bars 27 are mounted on the flanges of the core, both top and bottom being secured by the rods 25 which pass through perforations therein and together with the supporting bars 26 serve to hold the sides of the core very rigid and insure an even thickness in the walls of the vault. Said bars are adjustable by a series of hoies in their overlapping ends and a pin 28 inserted therein.

The top or lid of the vault is formed by l I- I 4 N more are secures o; nw' v53 slots 34 secured by tapered pins 35 as described for the structure of the body mold.

bodymold so in the structure of the core of the top mold, aseries of registering perforations 43 are formed in the flanges and securing bolts 44 are used in making the adjustments to form a mold of the size desired. The end sections 30 are of a considerably greater height than the side sections 31, in order to provide for the arch formation of the vault top. Said arch is provided for in the structure of the core by cross bars 45 which rest at intervals on the top of the inturned flanges of the side and corner sections and support a top composed of several steel plates as shown. The end plates 47 have flanges covering the ends and extend toward each end of the core for a considerable distance but not far enough to overlap the work. In order to stiffen the sides and ends of said core, brace bars 50 are mounted in recesses in the back edge of vertical supports or braces 51, said brace bars being formed of angle-iron and with the edge of their horizontal angle engaging in a notch in the ends of said braces 51, as'best shown in Figs. 14 and 15, forming an anterlocking brace which affords a very rigid support for the central portion both of the sides and ends of said core. By this means the walls of the top as well as the body of the structure are made of uniform thickness and true, insuring a good fit and avoiding trouble in setting.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent is:

l. A sectional vault mold constructed of metal comprising a rectangular outer frame formed of plates with outwardly turned flanges along. the upper and lower edges, vertically disposed angular braces secured to the outer sides of the plates at intervals along the length thereof, devices for adjustably connecting together the side and formed of plates with outwardly turned flanges along the upper and lower edges, vertically disposed angular braces secured to the outer sides of the plates at intervals along the length thereof, said sections having at their respective ends each a series of apertures in the flanges and a pin supporting member, tapering pins mounted on said supporting members and adapted to engage within the apertures of their respective adjacent sections for drawing the sections together and securing the same with a tight fit. an inner rectangular frame constructed of adjust-ably assembled metal sections, and members for centrally positioning said inner frame within the outer frame, substantially as set forth.

3. A sectional vault mold constructed of metal comprising arectangular inner frame formed of right angular corner sections, end sections and side sections, said sections having inturned flanges along the upper and lower edges thereof telescopically assembling the same, adjustably connected bars mounted on the flanges of said side sections, rods passing through said bars and the flanges of said side sections forming a rigidly connected structure, bars passing throughthe flanges of said end and corner sections forming connections therebetween, an outer rectangular frame, and a pair of angle bars adj ustably mounted on the upper flanges of the inner frame and supporting said inner frame on and centrally within said outer frame, substantially as set forth. In witness whereof, I have hereunto set my hand and seal at Indianapolis, Marion county, Indiana this 21st day of May, A. D.

nineteen hundred and twelve.
